* Use nix module system to check project arguments
This change uses the nix module system for the arguments to:
* `cabalProject'`
* `cabalProject`
* `stackProject'`
* `stackProject`
This will:
* Give an error when the name or type of an argument is incorrect
(currently misnamed args are quietly ignored).
* Fixes a problem with `projectCross` not having a way to pass different args to `cabalProject`
for different platforms. We can now use:
`({pkgs, ...}: { cabalProjectLocal = if pkgs.stdenv.hostPlatform.isX then ... })`
